Description

本発明は塗装ブースに配設される塗料ミスト捕集装置に関するものである。 The present invention relates to a paint mist collecting device arranged in a painting booth.

例えば文献１に開示されているように、塗装ブースから吸引した排気を水と共にベンチュリーに導き、ベンチュリーで霧化した水の微粒子で排気中に含まれる塗料ミストを捕捉する湿式の塗料ミスト捕集装置が従来から広く使用されている。
湿式の塗料ミスト捕集装置に対し、多孔体や衝突板で塗料ミストを捕捉する乾式の塗料ミスト捕集装置が近年使用されるようになった。乾式の塗料ミスト捕集装置は、循環水ポンプの駆動電力を必要としない点で、従来の湿式塗料ミスト捕集装置に比べて省エネを実現できるという利点がある。
塗装ブースの下部に配設される乾式の塗料ミスト捕集装置であって、入口と出口が水平に差し向けられた分離ユニットと、分離ユニットを積載すると共に分離ユニットの出口に連通する通風路を有する台車と、塗装ブースの下部に配設されると共に台車が有する通風路の端部に着脱可能に接続される固定通風路と、固定通風路の端部に連通する排気ファンとを備えることを特徴とする塗料ミスト捕集装置が特許文献２に開示されている。 For example, as disclosed in Document 1, a wet paint mist collecting device that guides the exhaust sucked from the painting booth to the Venturi together with water and captures the paint mist contained in the exhaust with fine particles of water atomized by the Venturi. Has been widely used in the past.
In recent years, a dry paint mist collector that captures paint mist with a porous body or a collision plate has been used as opposed to a wet paint mist collector. The dry paint mist collecting device has an advantage that it can realize energy saving as compared with the conventional wet paint mist collecting device in that it does not require the driving power of the circulating water pump.
A dry paint mist collector installed at the bottom of the painting booth, which has a separation unit with the inlet and outlet oriented horizontally, and a ventilation path for loading the separation unit and communicating with the outlet of the separation unit. It is provided with a trolley to be provided, a fixed ventilation passage which is arranged at the lower part of the painting booth and is detachably connected to the end of the ventilation passage of the trolley, and an exhaust fan which communicates with the end of the fixed ventilation passage. A characteristic paint mist collecting device is disclosed in Patent Document 2.

特許第３１９３５１１号公報Japanese Patent No. 3193511 特表２０１６−５３８１１８号公報Special Table 2016-538118

特許文献２の塗料ミスト捕集装置には、分離ユニットの入口と出口が水平に差し向けられているので、処理能力を高めるために分離ユニットを上下に多段配設する必要があり、塗料ミスト捕集装置の高さが大になり、塗装ブース下部スペースの高さが大になり、ひいては塗装ブースの高さが大になるという問題がある。
本発明は上記問題に鑑みてなされたものであり、塗装ブースの下部に配設される乾式の塗料ミスト捕集装置であって、入口と出口を備える分離ユニットと、分離ユニットを積載すると共に分離ユニットの出口に連通する通風路を有する台車と、塗装ブースの下部に配設されると共に台車が有する通風路の端部に着脱可能に接続される固定通風路と、固定通風路の端部に連通する排気ファンとを備える塗料ミスト捕集装置において、処理能力を高めても塗装ブースの高さの増大を招かない塗料ミスト捕集装置を提供することを目的とする。 In the paint mist collecting device of Patent Document 2, since the inlet and the outlet of the separation unit are horizontally directed, it is necessary to arrange the separation units in multiple stages vertically in order to increase the processing capacity, and the paint mist is collected. There is a problem that the height of the collector becomes large, the height of the space under the painting booth becomes large, and the height of the painting booth becomes large.
The present invention has been made in view of the above problems, and is a dry paint mist collecting device arranged at the bottom of a painting booth, in which a separation unit having an inlet and an outlet and a separation unit are loaded and separated. A trolley with a ventilation passage that communicates with the outlet of the unit, a fixed ventilation passage that is arranged at the bottom of the painting booth and is detachably connected to the end of the ventilation passage of the trolley, and at the end of the fixed ventilation passage. It is an object of the present invention to provide a paint mist collecting device provided with an exhaust fan that communicates with the paint mist, which does not increase the height of the painting booth even if the processing capacity is increased.

上記課題を解決するために、本発明においては、塗装ブースの下部に配設される乾式の塗料ミスト捕集装置であって、入口が上方へ出口が下方へ差し向けられた分離ユニットと、分離ユニットを積載すると共に分離ユニットの出口に連通する通風路を有する台車と、塗装ブースの下部に配設されると共に台車が有する通風路の端部に着脱可能に接続される固定通風路と、固定通風路の端部に連通する排気ファンとを備えることを特徴とする塗料ミスト捕集装置を提供する。
入口が上方へ出口が下方へ差し向けられた分離ユニットは、水平面内で前後左右に多数配設することにより処理能力を高めることができる。従って処理能力を高めても、塗料ミスト捕集装置の高さは増大せず、塗装ブース下部スペースの高さは増大せず、塗装ブースの高さは増大しない。 In order to solve the above problems, in the present invention, it is a dry paint mist collecting device arranged in the lower part of the painting booth, and is separated from a separation unit in which the inlet is directed upward and the outlet is directed downward. Fixed with a trolley that has a ventilation passage that loads the unit and communicates with the outlet of the separation unit, and a fixed ventilation passage that is arranged at the bottom of the painting booth and is detachably connected to the end of the ventilation passage of the trolley. Provided is a paint mist collecting device characterized by including an exhaust fan communicating with an end of a ventilation path.
The processing capacity can be increased by arranging a large number of separation units whose inlets are directed upward and whose outlets are directed downward in the horizontal plane. Therefore, even if the processing capacity is increased, the height of the paint mist collecting device does not increase, the height of the space under the coating booth does not increase, and the height of the coating booth does not increase.

本発明の好ましい態様においては、塗料ミスト捕集装置は、固定通風路と台車の通風路との連通を遮断可能なシャッターを備える。
使用済みの分離ユニットを積載した台車を、未使用の分離ユニットを積載した台車に取り替える際に、シャッターを作動させて、一時的に固定通風路と台車の通風路との連通を遮断することにより、固定通風路への異物の侵入を防止できる。
本発明の好ましい態様においては、台車の通風路に出し入れ可能な塗料受け皿が配設されている。
分離ユニットから流下する塗料を塗料受け皿に貯留することができる。この結果、台車の通風路が塗料で汚れる事態の発生が防止される。
本発明の好ましい態様においては、分離ユニットは板紙で構成され内部に屈曲した空気通路が形成されている。
板紙で構成され内部に屈曲した空気通路が形成された分離ユニットは、軽量で扱い易く、使用後の処理も容易である。
本発明の好ましい態様においては、分離ユニットは、複数の細長開口と前記各細長開口を間に挟んで周縁から前記細長開口の長手方向延在長の途中まで延在する複数のスリットとが形成された複数の第１横板と、複数の細長開口と前記各細長開口を間に挟んで周縁から前記細長開口の長手方向延在長の途中まで延在する複数のスリットとが形成された複数の第２横板と、複数の細長開口と前記各細長開口を間に挟んで周縁から前記細長開口の長手方向延在長の途中まで延在する複数のスリットとが形成された複数の縦板とを備え、第１横板と第２横板とが隙間を隔てて交互に配設されて横板集合体を形成し、横板集合体内において第２横板の隣接する細長開口の間の部位が第１横板の細長開口に対峙すると共に第２横板の細長開口が第１横板の隣接する細長開口の間の部位に対峙し、複数の縦板が隙間を隔てて配設されて縦板集合体を形成し、縦板集合体が自身のスリットを横板集合体のスリットに整列させて横板集合体に差し込まれ、横板集合体と縦板集合体とが協働して格子構造体を形成し、格子構造体内に屈曲した空気通路が形成され、前記格子構造体が横板の細長開口に対峙する開口が形成された箱体に収納されている。
開口とスリットとが形成された複数の横板で構成された横板集合体に、開口とスリットとが形成された複数の縦板で構成された縦板集合体が、互いのスリットを整列させて差し込まれた格子構造体は、折り畳みが可能なので、輸送や保管が容易である。
格子構造体内に屈曲した空気通路が形成されているので、塗装ブース排気は屈曲した空気通路を通過する。この結果、塗装ブース排気と横板、縦板との衝突回数が増加し、塗料ミスト捕集効率が向上する。
本発明の好ましい態様においては、固定通風路の台車の通風路との接続部に、空気圧で伸縮可能なチューブシールが取り付けられている。
台車の通風路を固定通風路に接続する際にはチューブシールを減圧し、台車の通風路とチューブシールとの摺動抵抗を低減させて接続作業を容易にし、接続後はチューブシールを加圧し、台車の通風路にチューブシールを圧接させて台車の通風路と固定通風路の接続部を強固にシールすることができる。
本発明の好ましい態様においては、台車内に且つ分離ユニットの出口の下方に、フィルターが配設されている。
台車内に且つ分離ユニットの出口の下方にフィルターを配設して、分離ユニットで捕捉しきれなかった塗料ミストを捕捉することにより、塗料ミスト捕集装置の機能が向上する。 In a preferred embodiment of the present invention, the paint mist collecting device includes a shutter capable of blocking communication between the fixed ventilation path and the ventilation path of the carriage.

塗料ミスト捕集装置Ａの作動と作用効果とを説明する。
塗装トンネル１０２内で、コンベヤ１０２ｂに載置されたワーク２００に対して図示しないスプレーガンから塗料が噴霧され、ワーク２００が塗装される。噴霧された塗料の一部は塗料ミストとなり、空気中に浮遊する。
図１に白抜矢印で示すように、空気供給室１０１から供給された下降空気流が塗料ミストを伴ってグレーチング１０２ａを通過し、開口１０４ａを通過し、開口１０４ａ直下の台車１０に平積みされた分離ユニット１の入口５ａに流入する。塗料ミストを伴う下降空気流は、図３（ａ）に白抜き矢印で示す塗装ブース排気流を形成して格子構造体４に流入し、図３（ｈ）に示すように、横板集合体２’、第1縦板集合体３’、第２縦板集合体３”を構成する板紙間の隙間と開口２ａ１、２ｂ１、３ａ１、３ｂ１とが形成する屈曲した空気通路を通過し、出口５ｂを通って分離ユニット１から流出する。前記屈曲した空気通路を通過する際に、横板２ａ、２ｂの開口２ａ１、２ｂ１に挟まれた部位や、縦板３ａ、３ｂの開口３ａ１、３ｂ１に挟まれた部位に塗装ブース排気が衝突し、前記部位に塗料ミストが付着して、塗料ミストが捕集される。塗料ミストが除去された塗装ブース排気が分離ユニット１から流出する。
台車１０の通風路１０ｂに出し入れ可能に配設された塗料受け皿１０ｃに分離ユニット１から流下した塗料が貯留される。
分離ユニット１から流出した塗装ブース排気は、開口１０ａを通って台車１０の通風路１０ｂに流入し、通風路１０ｂの端部から固定通風路２０に流入し、固定通風路２０の端部から排気ファン３０を通って、図示しない下流側の図示しない揮発性有機化合物除去装置を通って浄化された後、外部環境に放出される。
塗料ミストを捕捉した使用済みの分離ユニット１を積載した台車１０は、未使用の分離ユニット１を積載した台車１０に交換される。台車交換の際には、シャッター２０ａを作動させて、一時的に固定通風路２０と台車１０の通風路１０ｂとの連通を遮断する。 The operation and action effect of the paint mist collecting device A will be described.
In the painting tunnel 102, paint is sprayed from a spray gun (not shown) onto the work 200 placed on the conveyor 102b, and the work 200 is painted. Part of the sprayed paint becomes paint mist and floats in the air.
As shown by the white arrows in FIG. 1, the descending air flow supplied from the air supply chamber 101 passes through the grating 102a with the paint mist, passes through the opening 104a, and is stacked flat on the carriage 10 directly below the opening 104a. It flows into the inlet 5a of the separation unit 1. The descending air flow accompanied by the paint mist forms the paint booth exhaust flow indicated by the white arrow in FIG. 3 (a) and flows into the lattice structure 4, and as shown in FIG. 3 (h), the horizontal plate aggregate. Passes through a bent air passage formed by gaps and openings 2a 1 , 2b 1 , 3a 1 , 3b 1 between the paper sheets constituting 2', the first vertical plate assembly 3', and the second vertical plate assembly 3'. Then, it flows out from the separation unit 1 through the outlet 5b. When passing through the bent air passage, the portion sandwiched between the openings 2a 1 , 2b 1 of the horizontal plates 2a and 2b, and the vertical plates 3a and 3b. The paint booth exhaust collides with the part sandwiched between the openings 3a 1 , 3b 1 , and the paint mist adheres to the part, and the paint mist is collected. The paint booth exhaust from which the paint mist has been removed is separated unit 1. Outflow from.
The paint that has flowed down from the separation unit 1 is stored in the paint tray 10c that is arranged so that it can be taken in and out of the ventilation passage 10b of the carriage 10.
The paint booth exhaust gas flowing out of the separation unit 1 flows into the ventilation passage 10b of the carriage 10 through the opening 10a, flows into the fixed ventilation passage 20 from the end of the ventilation passage 10b, and is exhausted from the end of the fixed ventilation passage 20. After being purified through a fan 30 and a volatile organic compound removing device (not shown) on the downstream side (not shown), it is released to the external environment.
The trolley 10 loaded with the used separation unit 1 that has captured the paint mist is replaced with the trolley 10 loaded with the unused separation unit 1. When replacing the bogie, the shutter 20a is operated to temporarily cut off the communication between the fixed ventilation path 20 and the ventilation path 10b of the bogie 10.

塗料ミスト捕集装置Ａが備える入口５ａが上方へ出口５ｂが下方へ差し向けられた分離ユニット１は、水平面内で前後左右に多数配設することにより処理能力を高めることができる。従って塗料ミスト捕集装置Ａは、処理能力を高めても、高さが増大せず、塗装ブース下部スペースである設備室１０３の高さは増大せず、塗装ブース１００の高さは増大しない。
分離ユニット１内を塗装ブース排気が上から下へ流れるので、塗装ブース排気から分離された塗料の分離ユニット１からの流下が促進される。この結果、分離ユニット１の閉塞が阻止され、分離ユニット１の耐用期間が増加する。 The separation unit 1 provided with the paint mist collecting device A with the inlet 5a directed upward and the outlet 5b directed downward can be arranged in a large number in the horizontal plane in front, back, left and right to increase the processing capacity. Therefore, the height of the paint mist collecting device A does not increase, the height of the equipment room 103, which is the space under the painting booth, does not increase, and the height of the painting booth 100 does not increase even if the processing capacity is increased.
Since the paint booth exhaust flows from the top to the bottom in the separation unit 1, the flow of the paint separated from the paint booth exhaust from the separation unit 1 is promoted. As a result, the separation unit 1 is prevented from being blocked, and the useful life of the separation unit 1 is increased.

塗料ミストを捕捉した使用済みの分離ユニット１を積載した台車１０を、未使用の分離ユニット１を積載した台車１０に交換する際には、シャッター２０ａを作動させて、一時的に固定通風路２０と台車１０の通風路１０ｂとの連通を遮断するので、固定通風路２０への異物の侵入を防止できる。
分離ユニット１から流下した塗料が塗料受け皿１０ｃに貯留されるので、通風路１０ａが塗料で汚れるおそれは無い。
板紙で構成され内部に屈曲した空気通路が形成された分離ユニット１は、軽量で扱い易く、使用後の処理も容易である。
開口とスリットとが形成された複数の横板で構成された横板集合体２’に、開口とスリットとが形成された複数の縦板で構成された縦板集合体３’が、互いのスリットを整列させて差し込まれて構成された格子構造体４は、折り畳みが可能なので、箱体５と共に折り畳んで容易に輸送し、保管することができる。
格子構造体４内に形成された屈曲した空気通路を塗装ブース排気が通過するので、塗装ブース排気と横板２ａ、２ｂ、縦板３ａ、３ｂとの衝突回数が増加し、塗料ミスト捕集効率が向上している。
開口２ａ１、２ｂ１、３ａ１、３ｂ１を細長開口としたので、小開口を整列して複数設ける場合に比べて横板２ａ、２ｂ、縦板３ａ、３ｂの構成が簡素化されると共に、空気抵抗が低減してミスト捕集効率が向上している。 When replacing the trolley 10 loaded with the used separation unit 1 that has captured the paint mist with the trolley 10 loaded with the unused separation unit 1, the shutter 20a is operated to temporarily operate the fixed ventilation passage 20. Since the communication between the carriage 10 and the ventilation passage 10b of the carriage 10 is cut off, it is possible to prevent foreign matter from entering the fixed ventilation passage 20.
Since the paint flowing down from the separation unit 1 is stored in the paint tray 10c, there is no possibility that the ventilation passage 10a will be contaminated with the paint.
The separation unit 1 made of paperboard and having an air passage bent inside is lightweight, easy to handle, and easy to process after use.
A horizontal plate assembly 2'composed of a plurality of horizontal plates having openings and slits formed therein, and a vertical plate aggregate 3'consisting of a plurality of vertical plates formed of openings and slits are formed on each other. Since the lattice structure 4 formed by aligning the slits and being inserted is foldable, it can be folded together with the box body 5 for easy transportation and storage.
Since the paint booth exhaust passes through the bent air passage formed in the lattice structure 4, the number of collisions between the paint booth exhaust and the horizontal plates 2a, 2b, vertical plates 3a, and 3b increases, and the paint mist collection efficiency increases. Is improving.
Since the openings 2a 1 , 2b 1, 3a 1 , 3b 1 are elongated openings, the configurations of the horizontal plates 2a, 2b, and the vertical plates 3a, 3b are simplified as compared with the case where a plurality of small openings are arranged and provided. , Air resistance is reduced and mist collection efficiency is improved.

分離ユニット１の構成は、上記実施例の構成に限定されない。入口が上方へ出口が下方へ差し向けられた分離ユニットであれば良く、内部構造は格子構造体に限定されない。例えば目の粗い多孔質のフィルターでも良い。
図４に示すように、固定通風路２０の台車の通風路１０ｂとの接続部に、空気圧で伸縮可能なチューブシール２０ｂを取り付け、チューブシール２０ｂを図示しないエアシリンダに接続しても良い。
台車の通風路１０ｂを固定通風路２０に接続する際にはチューブシール２０ｂを減圧し、台車の通風路１０ｂとチューブシール２０ｂとの摺動抵抗を低減させて接続作業を容易にし、接続後はチューブシール２０ｂを加圧し、台車の通風路１０ｂにチューブシール２０ｂを圧接させて台車の通風路１０ｂと固定通風路２０の接続部を強固にシールすることができる。
図５に示すように、台車１０内に且つ分離ユニット１の出口５ｂと台車の開口１０ａの下方に、フィルター１０ｄを配設しても良い。
分離ユニット１で捕捉しきれなかった塗料ミストをフィルター１０ｄで捕捉することにより、塗料ミスト捕集装置Ａの機能が向上する。 The configuration of the separation unit 1 is not limited to the configuration of the above embodiment. The internal structure is not limited to the lattice structure as long as it is a separation unit in which the inlet is directed upward and the outlet is directed downward. For example, a coarse and porous filter may be used.
As shown in FIG. 4, a tube seal 20b that can be expanded and contracted by air pressure may be attached to a connection portion of the fixed ventilation path 20 with the ventilation path 10b of the carriage, and the tube seal 20b may be connected to an air cylinder (not shown).
When connecting the ventilation passage 10b of the trolley to the fixed ventilation passage 20, the tube seal 20b is depressurized to reduce the sliding resistance between the ventilation passage 10b of the trolley and the tube seal 20b to facilitate the connection work, and after the connection, The tube seal 20b can be pressurized and the tube seal 20b can be pressed against the ventilation passage 10b of the carriage to firmly seal the connection portion between the ventilation passage 10b of the carriage and the fixed ventilation passage 20.
As shown in FIG. 5, the filter 10d may be arranged in the carriage 10 and below the outlet 5b of the separation unit 1 and the opening 10a of the carriage.
By capturing the paint mist that could not be captured by the separation unit 1 with the filter 10d, the function of the paint mist collecting device A is improved.
